Application filed May 8,

' T0 aZZwizom 2'1 may concern.

Be it known that I, RALPH \V. WILSON, a citizen of the United States,and resident of the borough of Manhattan, in the city and State of NewYork, have invented a new and useful Improvement in Shaker Tops or Caps,(Case'IL) of which the following is a specification.

The object of my invention is to provide a novel shaker top or cap whichwill be practically powder tight, which will be very easy to manipulateand which will be inexpensive to manufacture and attractive in appearance.

A further objectisto providea shaker top or cap in which the shuttermember is held frictionally between the inner and outer perforated topor cap members and movable to open and close the perforations in saidinner and outer members, the location of the shutter member giving amuch neater appearance to the receptacle to which the top or cap isapplied and also protecting the shutter member from injury and fromexposure to dust and dirt.

A further object is to provide a shutter member which is held inposition by friction, thereby eliminating the necessity and expense ofusing a separate spring.

A still further object is to provide certain improvements in theconstruction, form and arrangement of the several parts whereby thedevice is materially simplified and rendered more effective for thepurposes intended.

Practical embodiments of my invention are represented in theaccompanying drawings, in which- Figure 1 represents in side elevation aportion of a receptacle with one-embodiment of my invention appliedthereto.

Fig. 2 represents a top or cap in top plan,

the regulable shutter member being shown in its closed position.

formed into the required shape. This top or cap comprises the innerperforated top or cap member 1, the outer perforated top or cap member 2and the interposed regulable shutter member The perforations 4 in theinner top or cap member 1 are always in alinement with the to or camember 2. The perforations 6 in the int rposed shutter member 3 arearranged to be brought into and out of alinement tions 4 and 5 as theshutter member 3 is moved back and forth into its opened and closedpositions.

This interposed shutter member 3 is frictionally held between the innerand outertop or cap members 1 and 2 and it is pro- :ldGd with oppositelydisposed finger pieces. '1 and 8, whlch project through slots 9 and 10in the side walls 11 of the outertop or cap member 2. These side walls11 ofthe outer top or cap member 2 overlap and are permanently securedto the side walls 12 of the inner top or walls 12 of the inner top orcap member may be an integral part of theside walls of the receptacle 13as shown in Figs. 1 t0 4; inclusive, or they may be screw-threaded asshown at 14 in Fig. 6, so that the top or cap may be removably attachedto the screwthreaded neck 15 of a bottle or other receptacle 16.

The inner top or cap member 1 is provided with a depressed portion 17and a raised peripheral portion 18. This raised peripheral portion 18 isomitted where the oppositely disposed finger pieces 7 and 8 are located.This raised peripheral portion 18 snugly engages the inner face of theouter top or cap member 2, thus forming a powder tight joint which isvery desirable.

The means which I have shown for yield ingly holding the shutter member3 in its opened or closed position is as follows:

The shutter member 3 is provided with a downwardly extended projection19 which is caused to snap into either oneof the two depressions 20 or21, in the face of the inner toplmember 1 as the shutter is moved intoits opened or closed position. The inner top or cap member 1 issufliciently yielding to allow the projection 19 to pass from one to theother of the depressions 20, 21.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts of my top or capmember 1. These side with the perforameans for yieldingly holding thecap without departing from the spirit and scope ofiny invention; hence Ido not wish to limit myself to the particular embodiments herein shownand described, but

What I claim is i 1. A shaker top or cap comprising perforated inner,outer and intermediate members of thin sheet material, said intermediatemember being provided with oppositely dis.- posed finger plecesprojecting throughthe sidewalls of the outer member for use inreciprocating the intermediate member, and

intermediate member opened or closed, said means being arranged tospring one of the members out of its normal position as the intermediatemember is reciprocated.

2. A shaker top or cap comprising perforatedinner, outer andintermediate members of thin sheet material, the inner member havinginte ralconverging side walls forming a shoul er and the outer memberhaving integral converging side walls overlapping and permanentlysecured to the side walls of the inner member, the intermediate memberbeing slidable back and forth across-the top of the cap between theinner and outer members, and the inner member being crowned tofrictionally press the intermedlate member against the outer member.

3. A shaker top or cap comprising perforated inner, outer andintermediate members of thin sheet material, the inner member havinginte al converging side walls forming a shoul er and the outer memberhaving integral converging side walls overlapping.
